Restrict network access to the kadmind service to trusted hosts only. Alternatively, disable kadmind and use the kadmin.local server-side command line tool for administrative operations if feasible. Since kadmind is not enabled by default and typically isolated, limiting exposure reduces risk.
Description
CVE-2026-112318 is a denial of service vulnerability in the MIT Kerberos 5 kadmind service used in Red Hat Enterprise Linux 10. The flaw occurs because the policy RPC stubs do not reject a NULL policy name, leading to a NULL pointer dereference and crash of the kadmind daemon when a remote authenticated user sends a crafted policy request with an empty policy name. This disrupts administrative operations but does not affect standard ticket-granting or authentication services.
